cargo xtask - no such subcommand: xtask

[neilsarkar]

Description
On trunk, cargo xtask is not found, but it is referenced in multiple places including https://github.com/gfx-rs/wgpu/wiki/Running-on-the-Web-with-WebGPU-and-WebGL

Repro steps

git clone https://github.com/gfx-rs/wgpu.git
cd wgpu
cargo xtask run-wasm --bin cube

Expected vs observed behavior

Expected to build and see the cube example running in browser. Instead got this:

$ cargo xtask run-wasm --bin cube
error: no such subcommand: `xtask`

	Did you mean `apk`?

	View all installed commands with `cargo --list`

Extra materials

It appears that the .cargo/config.toml that supports xtask was removed here: #4107

For beginners, the missing .cargo/config.toml can be hard to debug, especially since the project doesn't use the workspace setup suggested by https://github.com/matklad/cargo-xtask

Was this intentional? If so I can raise a separate issue about updating the documentation to reflect the removal of the xtask alias.

Platform

rustc 1.65.0 (897e37553 2022-11-02)
Mac OS Ventura 13.5.2

That absolutely doesn't seem intentional. cc @OptimisticPeach

We'd absolutely accept a PR to re-add it.

thanks! submitted a pr reversing that deletion ^

Oops, yup, I 100% didn't intend on deleting that -- I was using .cargo/config.toml to temporarily let CLion know that I'm compiling with WASM as the target, so removing that was part of my cleanup however apparently I forgot to notice that there were extra things in that file, other than the config I was adding 😅.
